Mexico to southern Brazil (Fern‡ndez 2004). Costa Rica: wet forest habitats on both slopes to 1300m elevation.
This species is mainly known from Winkler samples of sifted litter from the forest floor. It is relatively common in Winkler samples from lowland and mid-elevation wet forest habitats. It is less often collected using other methods. Nichole Barger made one collection of urichi while baiting at La Selva Biological Station. Bill Eberhard observed a flight of males from a nest in the ground near his home in Cerros de Escazu. Nevermann found the type series of nevermanni (now a junior synonym of urichi) in a rotten log, in company with Pachycondyla stigma.
